【摘要】：张家界大峡谷玻璃桥是一座主缆跨度430m的空间索面人行悬索桥。桥址位于喀斯特岩溶地貌区域,针对桥位处特殊的地形地貌和地质情况,东侧锚碇采用重力式锚,基础为明挖扩大基础(东南侧采用矩形扩大基础,东北侧采用阶梯式扩大基础);西侧锚碇采用锚塞体截面线性变化的隧道式锚,锚塞体长度为13.5m。桥塔塔柱均为圆环形钢筋混凝土独柱结构,每根塔柱均采用4根直径1.2m的人工挖孔灌注桩基础。桥墩采用桩柱式带盖梁的框架墩结构,每个墩柱下为直径1.5m的挖孔灌注桩。
[Abstract]:Zhangjiajie Grand Canyon Glass Bridge is a space cable pedestrian suspension bridge with a span of 430m. The bridge site is located in the Karst geomorphological area. In view of the special topographic, geomorphological and geological conditions at the bridge site, the gravity anchor is used in the east Anchorage, which is based on open excavation and expansion foundation (rectangular expansion foundation is used in the southeast side). On the northeast side, the stepped expansion foundation is adopted); The west side Anchorage adopts tunnel anchor with linear variation of anchor plug section, and the length of anchor plug body is 13.5 m. The tower columns of the bridge are circular reinforced concrete single column structures, and four artificial excavated cast-in-place pile foundations with a diameter of 1.2 m are used in each tower column. The pier adopts pile-column frame pier structure with cover beam, and each pier column is an excavated cast-in-place pile with a diameter of 1.5 m.
